CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 735,695, dated Augusti1, 1903.

Application filed October 22, 1902. Serial No. 12 8,345. (No model.)

To aZZ whom it. rnayconoern:

Be it known that I, PHILIP BAKER, a citizen of the United States,residing at Memphis, in the county of Scotland and State of Missouri,haveinvented a new and useful (Jar- Coupler, .of which the following isa specification.

The invention relates to improvements in car-couplers.

The object of the present invention is to improve the construction ofcar-couplers and to provide a simple, inexpensive, and efficient one ofgreat strength and durability, adapted to be readily applied to a carand capable of automatically coupling when two cars come together andadapted to be readily uncoupled without going between the cars.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out inthe claims hereto appended.

. In the drawings, Figure 1 is a perspective view of a car-couplingconstructed in accordance withthis invention. Fig. 2 is a reverse planview of the same. Fig. 3 is a longitudinal sectional view.

Like numerals of reference designate corresponding parts in all thefigures of the drawings. V

1 designates a draw-head provided with a shank ordraW-bar 2, which isdesigned to be mounted on a car in the usual manner. The draw-head 1 isprovided at one side with a recess, forming upper and lower ears 3,which are perforated for the reception of a knucklepin 4. The recessreceives a shank or reduced portion 5 of a hook or knuckle 6, which ispivoted to the draw-head by the knuckle-pin and which is adapted toswing laterally in coupling and in uncoupling. The knuckle or hook,which is provided with a hook-shaped engaging portion, may be arrangedeither at the right or left hand side of the draw-head,which is providedwith aflat front face 7 and which formsan efficient bumper. The outerend of the knuckle is provided with a link opening or cavity 8, and ithas acoupling-pin perforation 9, adapted to receive the ordinarycoupling-pin for enabling the car-coupling to be connected with carshaving the ordinary pin-and-link carcoupling. The pivoted hook orknuckle is provided at its lower face with a depending pivot or stud 10,to which is connected one arm of a bell-crank lever 11, which isfulcrumed at its angle on a depending pivot or stud 12 of the draw-head.The other arm of the bell-crank lever is connected with aspring-actuated rod or plunger 13, passing through an opening of a lugleof the shank or draw-bar of the draw-head and having its outer endsenlarged and bifurcated to receive the adjacent arm. of the bell-cranklever. The sides of the bifurcation are perforated for the reception ofapivot 15, and the inner portion of the rod or plunger receives a coiledspring 16, interposed between the ing 14 and a pin 17, which passesthrough the rod or plunger. The coiled spring holds the knuckle or booknormally closed or in an engaging position, and it prevents the knuckleor hook from becoming accidentally displaced or moved out of positionfor automatic coupling, thereby obviating the necessity of going betweencars and setting the knuckle or hook for automatic coupling. i

The pivot or studlO may be provided'with a shank 18, secured in a socketof thelower face of the pivoted knuckle or hook. The other pivot 12 istubular and is formed integral with an enlarged sleeve 19, securedwithin the perforation of the lower ear of the draw-head. The shank18,the enlarged sleeve 19, and an upper sleeve 19 may be secured in thedraw-head by a screw-thread or any other suitable means, and, ifdesired, these parts may be formed integral with the knuckle and thedraw-head;

The knuckle or-hook may be connected with an uncoupling-lever 2O byachain 21 or other flexible connection secured to a lug or ear 22 of theoutwardly-extending arm of the bell-crank lever; but the flexibleconnection may be arranged in any other desired manner. Theuncoupling-lever is fulcrumed between its ends beneath the car 23toenable the operation of couplingto be "performed I either side or topof a car or from the platform 1 bell-crank lever pivoted at its elbowand having one of its arms disposed parallel of and connected to theknuckle, a spring-controlled rod connected to the other arm of the leverand operating to maintain the knuckle normally in its engagingposition,a releasing-lever, and operative connections between the sameand the knuckle; whereby the latter may be moved by the former, againstthe action of the spring-controlled rod, to a disengaging position.

2. A car-coupling comprising a draw-head provided at one side with ears,a sleeve secured Within one of the ears and having a depending tubularplvot, a knuckle-pin passing through the ears and through the tubularpivot, a knuckle mounted on the knucklepin and having a socket at itslower face, a stud secured within the socket and having 9. dependingpivot, a bell crank lever fulcrumed on the tubular pivot and receivingthe other pivot, and a spring-actuated rod or plunger connected with thebell-crank lever, substantially as described.

3. A car-coupling comprising a draw-head provided at one side with upperand lower cars, a tubular pivot depending from the lower ear, aknuckle-pin passing through the ears and through the tubular pivot, aknuckle connected with the draw-head by the knucklepin, a pivotdepending from the knuckle and having a shank secured to the same, alever fulcrumed on the tubular pivot and connected with the dependingpivot of the knuckle, and means for operating, the lever, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
